B.5.2:1 - Problem frame

Use this when. An anomaly, opportunity or probe question needs candidate explanations that can be compared on their present plausibility. State the question and generate its serious rivals. The first useful result is a qualified conjecture with its supports, fragilities and allowed use, or an honest abort, defer or split outcome.

An adequate present answer or action need not enter abduction merely to generate another research task. Use C.11 for a live choice among feasible actions and C.28 when a causal-support claim is needed. Abduction contributes candidate explanatory content; it is not the complete evidence synthesis or action decision.
